Description

Technical Field

[0001] The present application relates to the technical field of stamping dies, and in particular to a multi-item isothermal stamping die and a method, system, and storage medium for processing heating tubes thereof. Background Art

[0002] A stamping die is a processing tool widely used in industrial production. During the stamping process, temperature control of the die is crucial. Especially for the isothermal stamping process, the uniformity and stability of the die temperature directly affect the forming quality and accuracy of the product. A stamping die usually includes a die base, and the die base includes an upper die base, a lower die base, a left die base, and a right die base. The left die base and the right die base approach each other to clamp the product, and then the upper die base moves downward to press the left die base and the right die base to prevent the left die base and the right die base from moving. A plurality of heating tubes are arranged in the left die base and the right die base. After the heating tubes are energized and generate heat, the heat is transferred to the left die set and the right die set in the form of heat exchange, so that the left die base and the right die base are heated and raised in temperature, thereby heating and shaping the product.

[0003] In view of the above related technologies, during the heating process, there is a probability that the heating tubes are in poor contact with the die base, resulting in the heat of the heating tubes not being well transferred to the die base, or there is a probability that the heating tubes themselves have faults, resulting in insufficient heat generation, so that the die base is unevenly heated, resulting in uneven heating of the product during heating and forming, affecting the forming quality and accuracy of the product. Summary of the Invention

[0004] In order to provide stable and uniform heat to the die base, the present application provides a multi-item isothermal stamping die and a method, system, and storage medium for processing heating tubes thereof.

[0005] In a first aspect, the present application provides a method for processing heating tubes of a multi-item isothermal stamping die, adopting the following technical solution:

[0006] A method for processing heating tubes of a multi-item isothermal stamping die includes:

[0007] Sequentially detecting the current values of the connection wires connecting a plurality of heating tubes;

[0008] Grouping the current values that are not less than the current threshold among all the current values according to a preset rule to form N data sets;

[0009] Subtracting the current value in each data set from the average value of the corresponding data set to obtain a deviation value;

[0010] Judging whether there is a deviation value greater than a preset deviation value;

[0011] If so, marking the connection wire corresponding to the current value with the deviation value greater than the preset deviation value as the target wire;

[0012] When the difference between the voltages at both ends of the heating tube corresponding to the target wire and the preset voltage is greater than the preset voltage difference, mark the heating tube corresponding to the target wire as the target heating tube;

[0013] Control the target heating tube according to a preset control method.

[0014] By adopting the above technical solution, when the heating tube is working, the current values of the heating tube are detected in sequence, and the current values not less than the current threshold are grouped to form N data sets. Then, each current value in each data set is subtracted from the average value of the data set where it is located to obtain a deviation value, and by judging whether there is a current value with a deviation value greater than the preset deviation value. If so, it indicates that the current value of the connecting wire corresponding to this current value is low, and further indicates that there may be a fault in this circuit. Then, mark this connecting wire as the target wire. When it is determined that the difference between the voltages at both ends of the heating tube corresponding to the target wire and the preset voltage is greater than the preset voltage difference, it indicates that the heating tube may have a fault. Therefore, mark this heating tube as the target heating tube and control the target heating tube through a preset control method, so as to provide stable and uniform heat for the die holder.

[0015] Optionally, the step of controlling the target heating tube according to a preset control method includes:

[0016] Obtain the temperature data of several detection points in the target heating tube according to a preset detection order;

[0017] Define the detection points where the temperature data is greater than the temperature upper limit threshold or less than the temperature lower limit threshold as temperature abnormal points;

[0018] Judge whether the number of the temperature abnormal points is greater than a preset upper limit number;

[0019] If so, when the temperature data of the temperature abnormal points is less than the temperature lower limit threshold, increase the power of the target heating tube to the preset power;

[0020] If not, judge whether the number of the temperature abnormal points is less than a preset lower limit number;

[0021] If so, execute the heating tube control step, and the heating tube control step includes: when the temperature data of the temperature abnormal points is less than the temperature lower limit threshold, control the position of the target heating tube in the die holder according to the first control method; when the temperature data of the temperature abnormal points is greater than the temperature upper limit threshold, control the position of the target heating tube in the die holder according to the second control method.

[0022] By adopting the above technical solution, by obtaining the temperature data of the detection point, it is possible to determine whether the detection point is a temperature anomaly point based on the temperature data. When the number of temperature anomaly points is greater than the preset upper limit number, and the temperature data of the temperature anomaly points is less than the lower temperature threshold, the power of the heating tube is increased to the preset power to improve the insufficient heating situation. When the number of temperature anomaly points is less than the preset lower limit number, it indicates that there is insufficient temperature or local overheating in the heating tube. Therefore, when the temperature data of the anomaly point is less than the upper temperature threshold, the position of the target heating tube in the die holder is controlled according to the first control method to improve the situation of insufficient local temperature of the heating tube; when the temperature data of the anomaly point is greater than the upper temperature threshold, the position of the target heating tube in the die holder is controlled according to the second control method, and the local overheating situation of the heating tube is improved through the heat exchange principle.

[0023] Optionally, the step of controlling the position of the target heating tube in the die holder according to the first control method includes:

[0024] Obtain the first position information of the temperature anomaly point on the target heating tube;

[0025] Calculate the first interval length occupied by the temperature anomaly point on the target heating tube according to the first position information;

[0026] Reciprocally move the position of the target heating tube in the die holder according to the first interval length and at the first preset frequency.

[0027] By adopting the above technical solution, when there is local insufficient temperature in the target heating tube, by obtaining the first position information of the temperature anomaly point on the target heating tube, and obtaining the first interval length according to the first position information, which is the length of the local insufficient heating area, the position of the target heating tube in the die holder is reciprocally moved according to the first interval length, so that the heating area of the target heating tube can transfer heat to the die holder according to the heat exchange principle to heat the corresponding die holder at the insufficient temperature area, to make up for the situation of local insufficient temperature of the target heating tube.

[0028] Optionally, the step of controlling the position of the target heating tube in the die holder according to the second method includes:

[0029] Obtain the second position information of the temperature anomaly point on the target heating tube;

[0030] Calculate the second interval length occupied by the temperature anomaly point on the target heating tube according to the second position information;

[0031] Judge whether the second interval length is less than the bottom perimeter of the target heating tube;

[0032] If so, reciprocally move the position of the target heating tube in the die holder according to the second interval length and at a second preset frequency;

[0033] If not, rotate the target heating tube according to a preset rotation frequency to uniformly heat the mold.

[0034] By adopting the above technical solution, when the target heating tube is locally bent, heat cannot be well transferred into the die holder, resulting in local insufficient temperature in the die holder while the target heating tube is locally overheated. Therefore, the second position information of the temperature anomaly point is obtained, and the second interval length is calculated according to the second position information. When the second interval length is less than the bottom perimeter of the target heating tube, the position of the target heating tube is reciprocally moved to transfer heat to the area with insufficient temperature in the die holder in the form of heat exchange; when the second interval length is greater than the bottom perimeter of the target heating tube, the target heating tube is rotated at a preset rotation frequency so that the side of the locally bent area in contact with the die holder can heat the die holder area corresponding to the non-contact side, thereby improving the situation of local insufficient temperature in the die holder.

[0035] Optionally, the step of calculating the second interval length occupied by the temperature anomaly point on the target heating tube according to the second position information includes:

[0036] Form a scatter plot based on the second position information of the detection points and the temperature data, and fit the scatter plot to obtain a curve graph;

[0037] Intersect the curve graph with a preset temperature line to obtain a first intersection point and a second intersection point;

[0038] Extract the abscissas of the first intersection point and the second intersection point to obtain a first abscissa and a second abscissa;

[0039] Obtain the second interval length by calculating the absolute value of the difference between the first abscissa and the second abscissa.

[0040] By adopting the above technical solution, a scatter plot is formed based on the second position information and the temperature data, and the scatter plot is fitted to obtain a curve graph, which can reflect the change trend of the temperature of the target heating tube along the length direction through the curve graph. By intersecting the curve graph with a preset temperature line to obtain a first intersection point and a second intersection point, the second interval length can be obtained more accurately.

[0041] Optionally, when the current value of the connecting wire is less than the current threshold, mark the heating tube corresponding to the connecting wire as a problematic heating tube;

[0042] Mark the heating tubes among several said heating tubes, whose distances from the problematic heating tube are within a preset distance range, as temporary heating tubes;

[0043] Increase the power of the temporary heating tubes in sequence according to a preset order.

[0044] By adopting the above technical solution, when the current value of the connecting wire is less than the current threshold, it indicates that the circuit corresponding to the connecting wire is open, that is, the heating tube corresponding to the connecting wire is not working properly. Mark this heating tube as a problematic heating tube. Then, mark the heating tubes among several heating tubes, whose distances from the problematic heating tube are within a preset distance range, as temporary heating tubes. By increasing the power of the temporary heating tubes in sequence according to a preset order, the heat lacking due to the malfunction of the problematic heating tube can be compensated, making the overall heat of the die base stable.

[0045] Optionally, the step of increasing the power of the temporary heating tubes in sequence according to a preset order includes:

[0046] Obtain the distance data of each said temporary heating tube to the problematic heating tube;

[0047] Form a distance data set according to the distance data in ascending order;

[0048] Determine a preset duration according to the distance data in the distance data set and a preset coefficient;

[0049] Execute the power increasing step, and the power increasing step includes: increasing the power of the temporary heating tube according to the order of the distance data in the distance data set until reaching the corresponding preset duration;

[0050] Repeat executing the power increasing step until the die heating ends.

[0051] By adopting the above technical solution, by increasing the power of the temporary heating tubes in sequence until reaching the preset duration, temperature compensation can be performed on the die base where the problematic heating tube is located in the form of heat exchange through the temporary heating tubes, so as to prevent uneven heating of the die base.

[0052] In a second aspect, the present application provides a heating tube processing system for a multi-item isothermal stamping die, adopting the following technical solution:

[0053] A heating tube processing system for a multi-item isothermal stamping die includes an acquisition module for acquiring current values, temperature data, first position information, second position information, and distance data;

[0054] A memory for storing the program of the heating tube processing method for the multi-item isothermal stamping die;

[0055] A processor, and a program in the memory can be loaded and executed by the processor to implement the heating tube processing method for the multiple isothermal stamping dies.

[0056] By adopting the above technical solution, when the heating tube is working, the current value of the heating tube is sequentially detected, and the current values not less than the current threshold are grouped to form N data sets. Then, each current value in each data set is subtracted from the average value of the data set where it is located to obtain a deviation value. By judging whether there is a current value with a deviation value greater than the preset deviation value, if so, it indicates that the current value of the connecting wire corresponding to this current value is low, and further indicates that there may be a fault in this circuit. Then, this connecting wire is marked as the target wire. When it is determined that the difference between the voltage at both ends of the heating tube corresponding to the target wire and the preset voltage is greater than the preset voltage difference, it indicates that the heating tube may have a fault. Therefore, this heating tube is marked as the target heating tube and is controlled by a preset control method to control the target heating tube, so as to provide stable and uniform heat for the die base.

[0057] In a third aspect, the present application provides a multiple isothermal stamping die, adopting the following technical solution:

[0058] A multiple isothermal stamping die includes a power control cabinet, and the power control cabinet includes a memory and a processor. A computer program capable of being loaded and executed by the processor to implement any one of the above methods is stored on the memory.

[0059] In a fourth aspect, the present application provides a computer storage medium, which can store a corresponding program and has the characteristic of being convenient for realizing providing stable heat for the die base. The following technical solution is adopted:

[0060] A computer-readable storage medium stores a computer program capable of being loaded and executed by the processor to implement any one of the heating tube processing methods for the multiple isothermal stamping dies.

[0061] By adopting the above technical solution, when the heating tube is working, the current value of the heating tube is sequentially detected, and the current values not less than the current threshold are grouped to form N data sets. Then, each current value in each data set is subtracted from the average value of the data set where it is located to obtain a deviation value. By judging whether there is a current value with a deviation value greater than the preset deviation value, if so, it indicates that the current value of the connecting wire corresponding to this current value is low, and further indicates that there may be a fault in this circuit. Then, this connecting wire is marked as the target wire. When it is determined that the difference between the voltage at both ends of the heating tube corresponding to the target wire and the preset voltage is greater than the preset voltage difference, it indicates that the heating tube may have a fault. Therefore, this heating tube is marked as the target heating tube and is controlled by a preset control method to control the target heating tube, so as to provide stable and uniform heat for the die base.

[0062] In summary, the present application includes at least one of the following beneficial technical effects:

[0063] When the heating tube is working, the current value of the heating tube is detected in sequence, and the current values not less than the current threshold are grouped to form N data sets. Then, each current value in each data set is subtracted from the average value of the data set where it is located to obtain a deviation value. By judging whether there is a current value with a deviation value greater than the preset deviation value, if so, it indicates that the current value of the connecting wire corresponding to this current value is low, and further indicates that there may be a fault in this circuit. Then, this connecting wire is marked as the target wire. When it is determined that the difference between the voltage at both ends of the heating tube corresponding to the target wire and the preset voltage is greater than the preset voltage difference, it indicates that the heating tube may be faulty. Therefore, this heating tube is marked as the target heating tube and the target heating tube is controlled by a preset control method, so as to provide stable and uniform heat for the die holder;

[0064] When the target heating tube is locally bent, the heat cannot be well transferred to the die holder, resulting in local temperature deficiency in the die holder, while the target heating tube has a local overheating situation. Therefore, the second position information of the temperature anomaly point is obtained, and the second interval length is calculated according to the second position information. When the second interval length is less than the bottom perimeter of the target heating tube, the target heating tube is reciprocally moved to transfer heat to the area with insufficient temperature in the die holder in the form of heat exchange; when the second interval length is greater than the bottom perimeter of the target heating tube, the target heating tube is rotated at a preset selection frequency, so that the side of the locally bent area in contact with the die holder can heat the die holder area corresponding to the non-contact side, so as to improve the situation of local temperature deficiency in the die holder;

[0065] By sequentially increasing the power of the temporary heating tube to reach the preset duration, the temperature compensation can be performed on the die holder where the problematic heating tube is located in the form of heat exchange through the temporary heating tube, so as to prevent uneven heating of the die holder.

[0075] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the following further describes the present application in detail with reference to the Figure 1-8 accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0076] The embodiments of the present application disclose a multi-item isothermal stamping die. Referring to Figure 1 , the multi-item isothermal stamping die includes a mold base 1, a relay cabinet 2 connected to the mold base 1, and a power control cabinet 3 connected to the relay cabinet. The mold base 1 includes a left mold base 11 and a right mold base (only the left mold base 11 is shown in the figure, and the right mold base is located on the back side of the left mold base 11). A plurality of heating tubes 12 are provided in both the left mold base 11 and the right mold base. The heating tubes are connected to the relay cabinet 2 and the power control cabinet 3 through connecting wires 4.

[0077] The embodiments of the present application disclose a method for processing heating tubes of a multi-item isothermal stamping die. Referring to Figure 2 , the method for processing heating tubes includes:

[0078] Step S201: Sequentially detect the current values of the connecting wires connecting a plurality of heating tubes.

[0079] The heating tube is a tube body that can generate heat and is in the shape of a long cylinder. The left mold base and the right mold base are both provided with heating holes for inserting the heating tubes. The heating tubes are inserted into the heating holes, and the heating tubes generate heat and transfer the heat to the left mold base and the right mold base through heat exchange.

[0080] The connecting wire is a wire connecting the heating tubes.

[0081] Exemplarily, the total number of heating tubes is 20, among which 10 heating tubes are on the left mold base and 10 heating tubes are on the right mold base. By measuring the current values on the connecting wires in sequence, it is possible to determine whether there is a fault in the corresponding circuit according to the current values.

[0082] Step S202: Group the current values that are not less than the current threshold among all the current values according to a preset rule to form N data sets.

[0083] The current threshold is a preset constant and can be adjusted according to actual needs. On the other hand, when the current value passing through the connecting wire is less than the current threshold, it means that there may be an open circuit in the corresponding circuit.

[0084] The preset rule is used to group the current values corresponding to several connecting wires.

[0085] A data set is a set obtained by grouping the current values according to the preset rule.

[0086] Exemplarily, among 20 connecting wires, there is no connecting wire with a current value less than the current threshold. The 20 current values are randomly and evenly divided into 4 groups to form 4 data sets. Therefore, N takes the value of 4, and each data set contains 5 current values.

[0087] Exemplarily, among 20 connecting wires, if the current value corresponding to 1 connecting wire is less than the current threshold, it means that there may be an open circuit in the circuit corresponding to this current value. Therefore, the remaining 19 current values are divided into 4 groups to form 4 data sets. Each of the 3 data sets contains 5 current values, and the remaining 1 data set contains 4 current values.

[0088] Step S203: Subtract the current value in each data set from the average value of the corresponding data set to obtain a deviation value.

[0089] Exemplarily, among 20 connecting wires, in the case where there is no connecting wire with a current value less than the current threshold, use A, B, C, and D to represent the 4 data sets respectively. Calculate the average values of A, B, C, and D respectively. Then subtract the current value in each data set from the average value of the data set corresponding to this current value to obtain a deviation value. The deviation value represents the deviation degree between the current value and the average value of the corresponding data set, and it can be used to reflect whether there is a fault in the circuit corresponding to the connecting wire through the deviation value.

[0090] Step S204: Determine whether there is a deviation value greater than the preset deviation value.

[0091] The preset deviation value is a preset constant and can be adjusted according to actual needs.

[0092] Exemplarily, there is a current value a1 in dataset A. The difference between a1 and the average value A1 of A is the deviation value Δa1. Among them, if Δa1 is greater than the preset deviation value ΔA1 of A, that is, Δa1 > ΔA1, it means that there is a deviation value greater than the preset deviation value in A.

[0093] Step S205: If so, mark the connecting wire corresponding to the current value with a deviation value greater than the preset deviation value as the target wire.

[0094] In another aspect, if there is no deviation value greater than the preset deviation value, it means that several heating tubes are all working normally and no operation is required.

[0095] Among them, when calculating the deviation value of the current value, the deviation value is obtained by subtracting the current value from the average value of the dataset corresponding to this current value and taking the absolute value. Therefore, there is a situation where after subtracting the average value from the current value, the obtained deviation value is positive and the deviation value is greater than the preset deviation value. Based on this situation, it means that there is a short - circuit situation in the circuit corresponding to this current value. Therefore, it is necessary to turn off this circuit through the power control cabinet. In this embodiment, the deviation value mainly considers the situation where the current value is less than the average value of the dataset.

[0096] Exemplarily, if the deviation value Δa1 between the current value a1 in dataset A and the average value A1 is less than the preset deviation value ΔA1, it means that the current value of the connecting wire corresponding to a1 is low, that is, there may be a fault in the circuit where this connecting wire is located. Mark the connecting wire corresponding to the current value a1 as the target wire.

[0097] Step S206: In the case where the difference between the voltage across the heating tube corresponding to the target wire and the preset voltage is greater than the preset voltage difference, mark the heating tube corresponding to the target wire as the target heating tube.

[0098] The preset voltage is a preset constant, related to the voltage across the heating tube corresponding to the target wire, and can be adjusted according to actual needs.

[0099] The preset voltage difference is a preset constant and can be adjusted according to actual needs.

[0100] By measuring the voltage across the heating tube corresponding to the target wire, and then comparing the difference between the voltage across this heating tube and the preset voltage with the preset voltage difference, it is possible to judge whether the fault point in the circuit is caused by this heating tube according to the comparison result.

[0101] In the case where the difference between the voltage across the heating tube corresponding to the target wire and the preset voltage is greater than the preset voltage difference, it means that there is a fault in the heating tube corresponding to the target wire. Therefore, mark this heating tube as the target heating tube.

[0102] In another aspect, if the difference between the voltages at both ends of the heating tube corresponding to the target wire and the preset voltage is not greater than the preset voltage difference, it indicates that the heating tube corresponding to the target wire has no fault, and the fault generation point is between the relay cabinet and the power control cabinet. Therefore, it is necessary to check for faults in the relay cabinet and the power control cabinet.

[0103] Step S207: Control the target heating tube according to a preset control method.

[0104] In the case where the target heating tube has a fault, control the target heating tube through a preset control method so as to continue to provide stable heat to the mold base.

[0105] By adopting the above technical solution, when the heating tube is working, the current values of the heating tube are detected in sequence, and the current values not less than the current threshold are grouped to form N data sets. Then, each current value in each data set is subtracted from the average value of the data set where it is located to obtain a deviation value, and by determining whether there is a current value with a deviation value greater than the preset deviation value. If so, it indicates that the current value of the connecting wire corresponding to this current value is too low, and further indicates that there may be a fault in this circuit. Then, this connecting wire is marked as the target wire. When it is determined that the difference between the voltage at both ends of the heating tube corresponding to the target wire and the preset voltage is greater than the preset voltage difference, it indicates that the heating tube may have a fault. Therefore, this heating tube is marked as the target heating tube and the target heating tube is controlled through a preset control method, so as to provide stable and uniform heat to the mold base.

[0106] Refer to Figure 3 , the steps of controlling the target heating tube according to a preset control method include:

[0107] Step S301: Obtain the temperature data of several detection points in the target heating tube according to a preset detection order.

[0108] Among them, several temperature sensors are evenly spaced along the length inside the target heating tube, and the points where the temperature sensors are located are the detection points. Exemplarily, 15 temperature sensors are arranged inside the target heating tube, so the number of detection points is 15. The preset detection order is to obtain the data of the temperature sensors in sequence from one end of the target heating tube close to the target wire towards the end of the target heating tube far from the target wire, so as to obtain the temperature data of the detection points in sequence.

[0109] Step S302: Define the detection points with temperature data greater than the temperature upper limit threshold or less than the temperature lower limit threshold as temperature abnormal points.

[0110] The temperature upper limit threshold is a preset constant, which is related to the temperature on the heating tube and can be adjusted according to actual needs.

[0111] The lower temperature threshold is a preset constant, related to the temperature on the heating tube, and can be adjusted according to actual needs.

[0112] When the temperature data is greater than the upper temperature threshold, it indicates that there is an overheating situation at the detection point, that is, there is a local overheating situation in the target heating tube. When the temperature data is less than the lower temperature threshold, it indicates that there is a temperature deficiency situation at the detection point, that is, there is a local temperature deficiency situation in the target heating tube. The detection points with overheating or temperature deficiency are defined as temperature anomaly points.

[0113] Step S303: Determine whether the number of temperature anomaly points is greater than the preset upper limit number.

[0114] The preset upper limit number is a preset constant, related to the number of temperature anomaly points on the target heating tube, and can be adjusted according to actual needs. Exemplarily, the preset upper limit number can be set to 10.

[0115] By determining whether the number of temperature anomaly points is greater than the preset upper limit number, in the case where the number of temperature anomaly points is greater than the preset upper limit number, step S304 is executed. In the case where the number of temperature anomaly points is not greater than the preset upper limit number, step S305 is executed.

[0116] Step S304: If so, when the temperature data of the temperature anomaly point is less than the lower temperature threshold, increase the power of the target heating tube to the preset power.

[0117] The preset power is a preset constant, related to the power of the heating tube. When the heating tube generates insufficient heat, the heat generation of the heating tube can be increased by increasing the power of the heating tube to the preset power, so as to increase the heat exchange amount with the mold base. The preset power can be adjusted according to actual needs.

[0118] If so, it means that the number of temperature anomaly points is greater than the preset number, indicating that most areas of the target heating tube may have overheating or temperature deficiency. Therefore, when the temperature data of the temperature anomaly point is less than the lower temperature threshold, it means that most areas of the target heating tube have insufficient temperature. At this time, by increasing the power of the target heating tube to the preset power, the heat generation amount is increased, so as to increase the heat exchange amount with the mold base. If the temperature data of the temperature anomaly point of the target heating tube is still less than the lower temperature threshold after increasing the power of the target heating tube to the preset power, the target heating tube can be replaced after the heating is completed.

[0119] On the other hand, there may be a certain gap between one side of the target heating tube and the inner wall of the heating hole, making it impossible to transfer the temperature of the target heating tube well, resulting in the temperature data of the temperature anomaly point being greater than the upper temperature threshold. Based on this situation, the target heating tube can be slowly rotated to make the target heating tube heat the mold base evenly.

[0120] Step S305: If not, determine whether the number of temperature anomaly points is less than a preset lower limit number.

[0121] The preset lower limit number is a preset constant and can be adjusted according to actual situations. Exemplarily, the preset lower limit number can be set to 5.

[0122] Step S306: If so, execute the step of controlling the heating tube, and the step of controlling the heating tube includes: when the temperature data of the temperature anomaly point is less than the temperature lower limit threshold, control the position of the target heating tube in the die base according to the first control method; when the temperature data of the temperature anomaly point is greater than the temperature upper limit threshold, control the position of the target heating tube in the die base according to the second control method.

[0123] If so, it means that the number of temperature anomaly points is less than the preset lower limit number, indicating that there is a situation of local temperature deficiency or local overheating in the heating tube. When the temperature data of the temperature anomaly point is less than the temperature lower limit threshold, it means that there is local temperature deficiency in the target heating tube. At this time, control the position of the target heating tube in the die base according to the first control method, so that the normal temperature area in the heating tube heats the die base corresponding to the temperature deficiency area in the form of heat exchange.

[0124] When the temperature data of the temperature anomaly point is greater than the temperature upper limit threshold, it means that there is a situation of local overheating in the target heating tube. Exemplarily, when the target heating tube is locally bent, the locally bent area cannot fit well with the inner wall of the heating hole, resulting in the heat in the locally bent area not being well transferred to the die base. On the one hand, it causes uneven heating of the die base, and on the other hand, it causes local overheating of the target heating tube. At this time, control the position of the target heating tube in the die base according to the second control method to uniformly heat the die base.

[0125] On the other hand, if the number of temperature anomaly points is greater than the preset lower limit number and less than the preset upper limit number, when the temperature data of the temperature anomaly point is less than the temperature lower limit threshold, the power of the target heating tube can be increased by the method of step S304.

[0126] When the temperature data at the temperature anomaly point is greater than the upper temperature threshold, based on this situation, for example, the target heating tube shows a long-area bend, such that the bent area cannot fit well with the inner wall of the heating hole. On the one hand, the heat on the bent side of the target heating tube cannot be transferred well into the mold base, resulting in overheating of a long area of the target heating tube. On the other hand, since the bent area cannot fit well with the inner wall of the heating hole, the target heating tube cannot exchange heat well with the mold base, causing uneven heating of the mold base. The target heating tube can be rotated so that the side of the bent area of the target heating tube that fits with the heating hole can rotate, making the heating of the mold base uniform. The specific steps can be referred to Figure 5 Examples.

[0127] By adopting the above technical solution, by obtaining the temperature data of the detection point, it is possible to judge whether it is a temperature anomaly point according to the temperature data. When the number of temperature anomaly points is greater than the preset upper limit number and the temperature data of the temperature anomaly points is less than the lower temperature threshold, the power of the heating tube is increased to the preset power to improve the insufficient heat generation situation. When the number of temperature anomaly points is less than the preset lower limit number, it indicates that there is a situation of insufficient temperature or local overheating in the heating tube. Therefore, when the temperature data of the anomaly point is less than the upper temperature threshold, the position of the target heating tube in the mold base is controlled according to the first control method to improve the situation of insufficient local temperature of the heating tube; when the temperature data of the anomaly point is greater than the upper temperature threshold, the position of the target heating tube in the mold base is controlled according to the second control method, and the principle of heat exchange is used to improve the situation of local overheating of the heating tube.

[0128] Referring to Figure 4 , the steps of controlling the position of the target heating tube in the mold base according to the first control method include:

[0129] Step S401: Obtain the first position information of the temperature anomaly point on the target heating tube.

[0130] The first position information is the information of the position of the temperature anomaly point on the target heating tube when the number of temperature anomaly points is less than the preset lower limit number and the temperature data of the temperature anomaly points is less than the lower temperature threshold. For example, if the temperature data of the 3rd to 5th detection points among 15 detection points in the target heating tube is less than the lower temperature threshold, the information of the positions of the 3rd to 5th detection points on the target heating tube is obtained.

[0131] Step S402: Calculate the first interval length occupied by the temperature anomaly point on the target heating tube according to the first position information.

[0132] The length of the first interval is the length of the interval occupied by all temperature anomaly points on the target heating tube. Exemplarily, for the 15 detection points in the target heating tube, the 3rd to 5th detection points are temperature anomaly points. Since the temperature sensors are evenly spaced along the length direction in the target heating tube, the length of the first interval is the corresponding distance length between the 3rd temperature sensor and the 5th temperature sensor, that is, the corresponding distance length between the 3rd detection point and the 5th detection point. Among them, the method for obtaining the length of the first interval can refer to Figure 6 the embodiment.

[0133] Step S403: Reciprocally move the position of the target heating tube in the mold base according to the length of the first interval and at a first preset frequency.

[0134] The first preset frequency is a preset constant, indicating the frequency of moving the target heating tube, which can be adjusted according to actual needs.

[0135] Exemplarily, the temperature data of the 3rd to 5th temperature anomaly points is less than the temperature lower limit threshold. According to the length of the first interval, the position of the target heating tube in the mold base can be reciprocally moved, and the moving length at one time is at least half of the length of the first interval. The first preset frequency can be to move the target heating tube once every 5 seconds, so that the part of the heating tube other than the 3rd to 5th temperature anomaly points can perform heat exchange on the area of the mold base corresponding to the 3rd to 5th temperature anomaly points to heat the mold base.

[0136] By adopting the above technical solution, when there is local insufficient temperature in the target heating tube, by obtaining the first position information of the temperature anomaly point on the target heating tube, and obtaining the length of the first interval according to the first position information, that is, the length of the local insufficient heating part, reciprocally move the position of the target heating tube in the mold base according to the length of the first interval, so that the heating area of the target heating tube can transfer heat to the mold base according to the heat exchange principle to heat the mold base corresponding to the place with insufficient temperature, so as to make up for the situation of local insufficient temperature in the target heating tube.

[0137] Referring to Figure 5 , the steps of controlling the position of the target heating tube in the mold base according to the second method include:

[0138] Step S501: Obtain the second position information of the temperature anomaly point on the target heating tube.

[0139] The second position information is the information about the position of the temperature anomaly point on the target heating tube when the number of temperature anomaly points is less than the preset lower limit number and the temperature data of the temperature anomaly points is greater than the temperature upper threshold. When the target heating tube has a local bend and the bent area cannot fit well with the inner wall of the heating hole, on the one hand, it makes the target heating tube unable to exchange heat well with the mold base on the bent side, so that the temperature of the target heating tube cannot be transferred to the mold base well, resulting in a higher temperature in the bent area of the target heating tube. On the other hand, the temperature on the bent side of the target heating tube cannot be transferred to the mold base well, resulting in uneven heating of the mold base.

[0140] Exemplarily, if the temperature data of the 7th to 9th detection points among the 15 detection points in the target heating tube is greater than the temperature upper threshold, then obtain the position information of the 7th to 9th detection points on the target heating tube, that is, the position information of the temperature anomaly point on the target heating tube, and the area corresponding to the 7th to 9th detection points on the target heating tube is the bent area of the target heating tube.

[0141] Step S502: Calculate the second interval length occupied by the temperature anomaly point on the target heating tube according to the second position information.

[0142] The second interval length is the interval length occupied by all temperature anomaly points on the target heating tube. Exemplarily, the 7th to 9th detection points among the 15 detection points in the target heating tube are temperature anomaly points, and the temperature sensors are evenly spaced along the length direction in the target heating tube. Therefore, the second interval length is the corresponding distance length between the 7th temperature sensor and the 9th temperature sensor, that is, the corresponding distance length between the 7th detection point and the 9th detection point.

[0143] Step S503: Determine whether the second interval length is less than the bottom perimeter of the target heating tube.

[0144] By comparing the second interval length with the bottom perimeter of the target heating tube, if the second interval length is less than the bottom perimeter of the target heating tube, then execute step S504; if the second interval length is not less than the bottom perimeter of the target heating tube, then execute step S505.

[0145] Step S504: If so, reciprocally move the position of the target heating tube in the mold base according to the second interval length and at the second preset frequency.

[0146] The second preset frequency is a preset frequency, indicating the frequency of moving the target heating tube, which can be adjusted according to actual needs.

[0147] If so, it means that the length of the second interval is less than the bottom circumference of the target heating tube. By reciprocally moving the position of the target heating tube in the mold base according to the second preset frequency, the mold base can be evenly heated. The target heating tube can be reciprocally moved by a manipulator. Exemplarily, the 7th detection point to the 8th detection point are temperature abnormal points, that is, the area corresponding to the 7th detection point to the 8th detection point on the target heating tube is the bending area of the target heating tube, and the length corresponding to the bending area is the length of the second interval. By moving the target heating tube, the target heating tube corresponding to the 1st detection point to the 6th detection point and the 9th detection point to the 15th detection point can heat the mold base corresponding to the bending area. Among them, the moving distance is at least half of the length of the second interval, the second preset frequency can be moving once every 5 seconds, and the moving time for one time is 5 seconds. By reciprocally moving to perform heat exchange on the mold base area corresponding to the bending area, the mold base is evenly heated.

[0148] Step S505: If not, rotate the target heating tube according to the preset rotation frequency to evenly heat the mold.

[0149] The preset rotation frequency is a preset constant, which is related to the frequency of rotating the target heating tube and can be adjusted according to actual needs.

[0150] If not, it means that the length of the second interval is not less than the bottom circumference of the target heating tube. Exemplarily, the 7th detection point to the 9th detection point are temperature abnormal points, the length of the template heating tube corresponding to the 7th detection point to the 9th detection point is the length of the second interval, and the length of the second interval is not less than the bottom circumference of the target heating tube. By rotating the target heating tube according to the preset rotation frequency, the bending area can rotate in the heating hole, so that the side of the bending area that fits the heating hole can rotate to perform heat exchange on the mold base, so as to avoid the problem that the side of the bending area that cannot fit the inner wall of the heating hole always stays in the same position, resulting in a low temperature of the mold base corresponding to this position.

[0151] By adopting the above technical solution, when the target heating tube is locally bent, the heat cannot be well transferred to the mold base, there is local temperature deficiency in the mold base, and the target heating tube is locally overheated. Therefore, the second position information of the temperature abnormal point is obtained, and the length of the second interval is calculated according to the second position information. When the length of the second interval is less than the bottom circumference of the target heating tube, the target heating tube is reciprocally moved to transfer heat to the place where the temperature of the mold base is insufficient in the form of heat exchange; when the length of the second interval is greater than the bottom circumference of the target heating tube, the target heating tube is rotated according to the preset selection frequency, so that the side of the locally bent area that fits the mold base can heat the mold base area corresponding to the non-fitting side, so as to improve the situation of local temperature deficiency in the mold base.

[0152] Refer toFigure 6 The steps of calculating the second interval length occupied by the temperature anomaly point on the target heating pipe according to the second position information include:

[0153] Step S601: Form a scatter plot based on the second position information and temperature data of the detection points, and fit the scatter plot to obtain a curve graph.

[0154] Among them, the relationship between the second position information and temperature data at the current moment is represented by the scatter plot, and the scatter plot is fitted to obtain a curve graph. The distribution law of the second position information and temperature data is intuitively shown through the curve graph.

[0155] Exemplarily, the second position information is used as the abscissa, and the temperature data is used as the ordinate. The zero point of the abscissa is one end of the target heating pipe close to the connecting wire, and the length of the target heating pipe is mapped to the abscissa. The position of the temperature sensor on the target heating pipe, that is, the position corresponding to the detection point on the target heating pipe, can be reflected by the abscissa. The temperature data of each detection point is used as the ordinate. Coordinate points of the detection points are formed with the second position information as the abscissa and the temperature data as the ordinate. Among them, the temperature change on the target heating pipe is continuous. By connecting the coordinate points of several detection points with a smooth curve, a curve graph is obtained, and the bending area of the target heating pipe can be reflected by the change of the curve graph.

[0156] Step S602: Intersect the curve graph with a preset temperature line to obtain a first intersection point and a second intersection point.

[0157] Calculate the tangent slope of the coordinate point corresponding to each detection point on the curve graph. Among all the coordinate points, along the positive direction of the abscissa, the coordinate point with the absolute value of the first tangent slope greater than the preset slope is marked as F1, and the coordinate point with the absolute value of the last tangent slope greater than the preset slope is marked as P1. The coordinate point after F1 is marked as F2, and the coordinate point before P1 is marked as P2. Among them, the preset slope is a preset constant, indicating the temperature change rate on the target heating pipe. The tangent slope greater than the preset slope indicates that the temperature change degree of this coordinate point is large. Combining with the curve graph, it can be inferred that the target heating pipe starts to bend from this coordinate point. Since the temperature change on the target heating pipe is continuous, F1 may be affected by F2, causing the temperature of F1 to increase. Similarly, P1 may be affected by P2, causing the temperature of P1 to increase. Therefore, when determining the second interval length, the midpoint F3 of the ordinates of F1 and F2 is taken, and the midpoint P3 of the ordinates of P1 and P2 is taken. And since the temperature change on the target heating pipe is continuous, the average value avg of the midpoint F3 and the midpoint P3 is taken. Therefore, the preset temperature line is a horizontal line with the ordinate being the average value avg. Through the intersection points of the horizontal line and the curve graph, a first intersection point and a second intersection point can be obtained.

[0158] Step S603: Extract the abscissas of the first intersection point and the second intersection point to obtain a first abscissa and a second abscissa.

[0159] Among them, the ordinate of the first intersection point is the average value avg. The abscissa of the first intersection point can be calculated through the curve graph to obtain the first abscissa. The ordinate of the second intersection point is the average value avg. The abscissa of the second intersection point can be calculated through the curve graph to obtain the second abscissa.

[0160] Step S604: Obtain the length of the second interval by calculating the absolute value of the difference between the first abscissa and the second abscissa.

[0161] By calculating the absolute value of the difference between the first abscissa and the second abscissa, that is, the length mapped to the abscissa from the first intersection point to the second intersection point, the length of the bending area of the target heating tube can be obtained based on this length, that is, the length of the second interval.

[0162] By adopting the above technical solution, a scatter plot is formed by the second position information and the temperature data, and the scatter plot is fitted to obtain a curve graph, which can reflect the change trend of the temperature of the target heating tube along the length direction through the curve graph. By intersecting the preset temperature line with the curve graph to obtain the first intersection point and the second intersection point, the length of the second interval can be obtained more accurately.

[0163] In the following embodiments, during the heating process of several heating tubes, the heating tubes may be damaged, resulting in insufficient total heating of the mold base and uneven heating. To solve this problem, refer to Figure 7 , a temporary heating method is provided, and this method includes:

[0164] Step S701: When the current value of the connecting wire is less than the current threshold, mark the heating tube corresponding to the connecting wire as a problematic heating tube.

[0165] Among them, when the current value of the connecting wire is less than the current threshold, it means that the circuit corresponding to the connecting wire is open. The heating tube corresponding to the connecting wire cannot perform heat exchange with the mold base to provide heat for the mold base, resulting in uneven heating of the mold base. Therefore, mark this heating tube as a problematic heating tube.

[0166] Step S702: Mark the heating tubes within a preset distance range from the problematic heating tube among several heating tubes as temporary heating tubes.

[0167] The preset distance range is a preset constant and can be adjusted according to actual needs.

[0168] Exemplarily, taking the position of the mold base where the problematic heating tube is located as the center and expanding outward, the heating tubes within the specified range are marked as temporary heating tubes. Herein, the specified range can be adjusted according to actual requirements. The temporary heating tubes can be used to make up for the lack of heat due to the inability of the problematic heating tube to heat.

[0169] Step S703: Sequentially increase the power of the temporary heating tubes according to a preset order.

[0170] Increase the power of the temporary heating tubes sequentially according to a preset order, so that several temporary heating tubes can alternately increase their power to make up for the heat at the mold base where the object heating tube is located.

[0171] By adopting the above technical solution, when the current value of the connecting wire is less than the current threshold, it indicates that the circuit corresponding to the connecting wire is open, that is, the heating tube corresponding to the connecting wire is not working properly, and this heating tube is marked as a problematic heating tube. Then, the heating tubes among several heating tubes whose distance from the problematic heating tube is within the preset distance range are marked as temporary heating tubes. By sequentially increasing the power of the temporary heating tubes according to a preset order, the lack of heat due to the inability of the problematic heating tube to work properly can be compensated, so that the overall heat of the mold base is stable.

[0172] Refer to Figure 8 , the step of sequentially increasing the power of the temporary heating tubes according to a preset order includes:

[0173] Step S801: Obtain the distance data of each temporary heating tube to the problematic heating tube.

[0174] The distance data is the straight-line distance from the temporary heating tube to the problematic heating tube. Exemplarily, the bottom center points of all temporary heating tubes and the problematic heating tube are mapped onto the same plane, and the distance from the point corresponding to each temporary heating tube to the point corresponding to the problematic heating tube is calculated to obtain the distance data.

[0175] Step S802: Form a distance data set according to the distance data in ascending order.

[0176] The distance data set is a set of data of the straight-line distances from all temporary heating tubes to the problematic heating tube. Exemplarily, the number of temporary heating tubes is 5, and the distance data from the 5 temporary heating tubes to the problematic heating tube are d1, d2, d3, d4, and d5 respectively. Among them, the magnitude relationship of the 5 distance data is: d3 < d2 < d4 < d5 < d1. Therefore, the distance data set is <d3, d2, d4, d5, d1>.

[0177] Step S803: Determine a preset duration according to the distance data in the distance data set and a preset coefficient.

[0178] The preset coefficient is related to the heat transfer efficiency in the die holder. The preset coefficient η can be calculated according to the heat attenuation model in the die holder. The relationship between the preset coefficient η and the distance data d is as follows: . Where α represents the heat attenuation coefficient of the die holder material. The preset duration t is: . Where t0 is the base duration, indicating the time required to raise the temperature at the die holder where the problem heating tube is located to the normal temperature value when the distance between the temporary heating tube and the problem heating tube is 0.

[0179] Step S804: Execute the power increase step, which includes: increasing the power of the temporary heating tube according to the order of the distance data in the distance data set until the corresponding preset duration is reached.

[0180] Exemplarily, according to the distance data set <d3, d2, d4, d5, d1>, first increase the power of the temporary heating tube corresponding to d3 to reach the preset duration t3, , so as to be able to perform heat compensation on the die holder where the problem heating tube is located. When the duration of increasing the power of the temporary heating tube corresponding to d3 reaches t3, stop increasing the power of the temporary heating tube corresponding to d3. Then increase the power of the temporary heating tube corresponding to d2 to reach t2, , so as to be able to perform heat compensation on the die holder where the problem heating tube is located. And so on, until the step of increasing the power of the temporary heating tube corresponding to d1 is completed.

[0181] Step S805: Repeat the power increase step until the mold heating is completed.

[0182] Repeat step S804, so as to be able to provide heat compensation to the die holder where the problem heating tube is located through the temporary heating tube to ensure the stability of the heat required by the die holder.

[0183] By adopting the above technical solution, by sequentially increasing the power of the temporary heating tube to reach the preset duration, it is possible to perform temperature compensation on the die holder where the problem heating tube is located in the form of heat exchange through the temporary heating tube, so as to prevent uneven heating of the die holder.

[0184] Based on the same inventive concept, an embodiment of the present application provides a heating tube processing system for a multi-item isothermal stamping die, including:

[0185] An acquisition module for acquiring current values, temperature data, first position information, second position information, and distance data;

[0186] A memory for storing the program of the above-mentioned heating tube processing method for the multi-item isothermal stamping die;

[0187] A processor, and the program in the memory can be loaded and executed by the processor to implement the heating tube processing method for the multi-item isothermal stamping die.

[0188] By adopting the above technical solution, when the heating pipe is working, the current value of the heating pipe is detected in sequence, and the current values not less than the current threshold are grouped to form N data sets. Then, each current value in each data set is subtracted from the average value of the data set where it is located to obtain a deviation value. By judging whether there is a current value whose deviation value is greater than the preset deviation value, if so, it indicates that the current value of the connecting wire corresponding to the current value is low, and further indicates that there may be a fault in this circuit. Then, the connecting wire is marked as the target wire. When it is determined that the difference between the voltage at both ends of the heating pipe corresponding to the target wire and the preset voltage is greater than the preset voltage difference, it indicates that the heating pipe may have a fault. Therefore, the heating pipe is marked as the target heating pipe and the target heating pipe is controlled by a preset control method, so as to provide stable and uniform heat for the die holder.
